SULKY-HARROW.

SPECIFICATION forming part of Letters Patent No. 372,651, dated November 8, 1887.

Application filed September 16, 1887. Serial No. 249,839. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM R. ARCHER, a citizen of the United States of America, and a resident of Green, in the county of Clay and State of Kansas, have invented certain new and useful Improvements in Sulky-Harrows, of which the following is a specification.

This invention relates to improvements in harrows of that character or class known as sulky-harrows, and it has for its object to simplify and lessen the cost of construction,

and at the same time to manipulate more conveniently, easily, and expeditiously the working parts thereof, whereby more work is ac complished in less time and with less expenditure of power and labor than has hitherto been done by barrows ordinarily.

\Vith these ends in view the invention consists in the novel construction and combination of the several parts, as will be hereinafter more particularly described, and specifically pointed out in the claims.

In the accompanying drawings, to which reference is had, and which fully illustrate my invention, Figure 1 is a side elevation of my improved sulky-harrow, and Fig. 2 is a rear View of the same.

Similar letters of reference indicate corresponding parts in the several figures.

a, a, and 1) indicate three longitudinal bars, the barb lying adjacent to the side bar, a, and between the two outer or side bars, a and a, and running parallel therewith, and which are rigidly secured and mounted upon an axle, A, provided with driving wheels 3 y. The forward ends of these bars a, a, and Z) is secured to a transverse front bar, 0, by lnortising and tenoning the ends of the bars a a b therein, or in any suitable manner. In the under side of the rear ends of the longitudinal parallel bars is transversely bored or formed holes d, having bearing-plates d secured below them to the under side of the rear ends of the bars a which is suspended, by means of connectingrods k, having eyes in their upper ends, which form connection with the eyes of the bent arms h of the rock-shaft 72, two obliquely-arranged rectangular harrows, Z l, which are connected together and side by side by means of the ordinary coupling. Permanently secured to each of these barrows, in the center and to the tops thereof, are two metallic bowed pieces, k, which are crossed, and at the same time run to a raised point in their centers in such a manner nearly resembling in form the letter X, to the apex or point of which the lower ends of said connecting-rods k are secured by means of eyes formed therein.

To the top of and near the forward end of the longitudinal bar bis rigidly secured a segment or semicircular plate, 9, notched for the purpose of engaging the lower end of an auxiliary latching rod or bar, 0, which has its lower end passing loosely through guides or Staples 0' 0 and secured by said staples to the center and one side of a hand-lever, e, the upper part of this latch rod or bar having an eye, f, therein, through which passes the lower turned or bent end of an auxiliary thumb lever, f, the lower end, also, of which passes through a hole formed in the hand-lever a, near its top, where it is pivotally or loosely secured in any suitable manner. The hand-lever c is also pivotally secured, by means of a screw, or by any suitable means, near its lower end, to the inner side and near the forward end of the longitudinal bar 1), and in juxtaposition to the segment 9, thus allowing the lower end of the latch-rod 0", which is secured to the hand-lever e, to traverse the segment and engage the notches therein when it is desired to adjust or raise and lower the harrows. One or more holes are formed in the lower end of the hand-lever 0, through which is passed and securely turned therein one end of an adjustable eonnectingrod, j, the other end of the rod j being connected by means of an eye to the U-shapcd bend or depression 11 in the rock-shaft h.

The forward ends of the harrows are provided with eyes or staples s s, secured in them, through which hooked eyes,s,formed upon one end otlinksa,are passed and loosely secured by the connection, the other hooked eyes or ends of said links forming a connection with a doubletree draft-bar or evener, by passing through holes in the ends and being loosely and securely turned within the holes.

To staples t, secured in the draft-bar d, by driving them in and clinching them on the opposite ends, is also connected one end each of four hitching or draft bar and barrow-suspending chains, m 0, having their oppositeends secured to staples or eyes t, secured to the under side of the transverse front bar, 0, and to the sides of the longitudinal side bars, a a, of the rectangular frame or body of the sulky, whereby the harrows are suspended at their forward ends, so as to give them a vertical and uniform adjustment when raised a'nd'lowered by means of the hand-lever 6. Connected to the center of the draft-bard by means of a link, 12, passing through a hole formed in the center of it and through a hole formed in the center of a doubletree, the said draft-bar or evener and doubletree are thus securely but loosely connected together. v

z indicates the draft-pole, the rear end of which is tenoned in a mortise in the center of the axle A, while the front or forward trans" verse bar, 0, of the rectangular body or frame further rigidly secures the pole near its center by its fitting snugly within a notch in thecenter and under side of the transverse bar 0. This pole is spliced together by means of a semi-link, 'v, the ends of the semi-link passing through both sections of the pole, and being screw-threaded at their ends theyengage screwthreaded nuts, which hold them together, the object being, it'it becomes necessary to economize space for housing, 800., that the sections can be disconnected.

Near the rear end of the draft-pole z is secured the driversseat w, to a spring-standard,

m, the lower end of the spring-standard being rigidly secured to the rear part of the draftpole.

ZZindicate two obliquely-constructed rectangular harrows, formed of a series of longitudinally obliquely-arranged bars, (1 q, having mortises or slots q q in their sides near each end, through which transverse obliquely-arranged short loars (f q are passed and mortised in the bars (1 q. These bars q q have also bored in each two holes,which are arranged in aligment with each other, near the obliquely-arranged bars 1 through which coupling rods 1' 1 are arranged and passed, on the inner ends of which hook-and-eye couplings are formed, as at g, which couple the harrows loosely together. The bars q q are provided with a series of teeth arranged transversely and obliquely with relation to the said bars (1 q, and in alignment with each other. On

the top and in the center of the harrows Z Z are it, however, may be briefly stated as follows:

As the machine is drawn along over the field, the harrows are consequently in their lowest position while harrowing; and when the machine gets to the end of the field, and it becomes necessary to turn and to harrow in the opposite direction, the attendant from his seat has only to grasp and draw the hand -lever toward him, which movement of the lever elevates the harrows uniformly and at all parts; and after they are'so elevated and he desires to maintain them in that position until he turns, he presses upon the auxiliary or small lever,

in the opposite direction to the movement of the hand-lever,which throws the lower end of the latch-rod in engagement with any one of the segmental notches, and, the harrows are held in their elevated position. A reversed movement of the hand lever and auxiliary thumb-lever gives the reversed movement to or lowers the harrows to the ground,or in their normal positions to return to harrowing. In turning the machine at corners or for cleaning the harrows, and for moving the machine from place to place, the manipulation of the parts above described is very conveniently and easily done without the necessity, of the attendant getting up from his seat or the neces sity of an assistant.

Having thus described my invention, what I claim, and""desire to secure by Letters Patent, 13-- The combinatiomwith the rectangular frame a a b c, of the rock-shaft h, provided in the center with the U shaped bend i, to which the lower end of the adjustable hand-lever e is connected by means of connecting-rod j, segment 7, auxiliary latclrrod' 0 thun1b-leverf, rods 70, connected to the ends of the shaft h at one end and the other end connected to Xshaped hows it of the harrows ll, the draftbar or evener d, connected to the rectangular frame and harrows, by means of the suspending-chains m 0, and links a n, all constructed, arranged, and operated as herein shown and described.
